Open pit mining Mining Methods 5 Open pit mines are used to exploit low grade, shallow ore bodies. However, some pits are quite deep – about 1 km. The mining rate is greater than 20,000 tonnes per day (tpd) but is usually much greater. Some pits operate at a rate of more than 100,000 tpd
Morenci Copper Mine, Arizona, USA
The open pit mine is approximately 5.4km in width from east to west and 7.4km in length from north to south. The final pit depth is expected to be approximately 4,450ft, ranging from 1,800ft to 6,250ft above sea level. Mining operations are carried out on 50ft benches with double benches where the pit slope permits.
